The Open Content Alliance (OCA) represents the collaborative efforts of a group of cultural, technology, nonprofit, and governmental organizations from around the world that will help build a permanent archive of multilingual digitized text and multimedia content. The OCA was conceived by the Internet Archive and Yahoo! in early 2005 as a way to offer broad, public access to a rich panorama of world culture.
The public domain is not contractually constructed. It just is. It cannot be made more free, only less free. And if we start a culture of licensing and enclosing the public domain (stuff that is actually already free, like the human genome) in the name of "freedom" we're playing a dangerous game.
